DIY Email Counting T-Shirt Gauges Your Popularity

Chris and Madeleine Ball created a t-shirt which incorporates an Arduino Lilypad, Bluetooth dongle, and an Android phone to send the number of unread emails in their inbox to the shirt, which will show up as illuminated LEDs via conductive threads. The shirt has 7 LEDs and can display up to 127 new messages. For most of us, 126 of those will be spam.

If you want to try and make one of your own, check out the project page to obtain the source code that runs on the Lilypad and the python script.
